TURBINE.

Toall whom t ma concern.' Be it known vt at I, EMIL ANDERSON, a

citizen of the United States of America, and

- frame are affixed side plates 12 and 13 each sectional side elevation of an engine embody# ing my invention. Fig. 2 is a sectional plan view showing the construction and arrange# ment of some of the parts, this section being taken through one of the controlling valves and its adjacent parts. In Fig. 3 I have shown the apparatus in sectional end elevation. A modified construction is illustrated in Fig. 4 in sectional end elevation on a` somewhat enlarged scale.

Like characters of reference designate cor.

responding parts in all of the figures.

10 designates an annular frame upon which the other parts of the apparatus are supported. This is open at 11 so that the exhaust motive fluid may pass out through it and through the base upon which it rests to the air or to acondenser. To this annular .of which is provided with a stuffing box` for the rotor' shaft 14 and support the bearings 15 and 16 respectively for this shaft.

The rotor comprises a hub 20 which is keyed t'o the shaft from which projects a ribbedflange 21. Two circumferentialrims 2223v extend to one side of flange 21, andv iat rings 24 and 25 parallel with iange' 21 are affixed to these rims respectively. j `'Ihese parts form ja double annular tr( m-`ghl ikev structure, of which the'open side ofthe outer` troughv'istoward'the axis-.of the rotor'. andl the open'side ,of the inner trough is :away

from the axis, so that the two troughs are open toward each-other. In each trough is a vplurality of rotor `rings which divide each trough into a plurality of parallel channels. The rotor rings in the outer trough are des- Specification of Ietters Patent.

-ignated try-26 and those in the inner trough by 27. The rotor rings are preferably corrugated so that the channels they form are wave-like. They may be held 1n place in any desired manner, such for example, as by the construction shown in application for patent Serial No. 714,905, iiled by me vided with transverse drainage channels dis- A construction for these drainage channels 1s also described in the aforesaid application for patent.

The side plate 13is constructed .to form an annular motive fluid chest 17 with which` the supply pipe 18 is connected-directly. At intervals about this chest are secured stationary nozzle blocks 30 which at intervals fill the space between the open sides of the troughs.l These are bored out to receive cylindrical sleeve valves 31 which are arranged to beL manually rotated, for example, by the handles 32. Each of these valves is perforated at 33 in that portion of it which crosses the It is also provided with a port 34 which may be brought into register with either an ad- Vance expansion nozzle 35 or a reverse nozzle 36, or into position to shut oif the motive fluid.

37 is a ring rotatably mounted between t-he Huid chest 17 and the nozzle blocks 30. A pinion 38 which meshes in gear teeth inthe side of ring 37 is connected with a :handle 39 by means of which the ring mayl be rotated. blocks.' 40, one in advance of each of the Aixed to this ring are 'nozzle blocks, and like Vthe latter these ,blocks fit the annular space between the :open sides of the rotor troughs. The for- 'ward end offeach nozzle block is beveled las shown, and between it and the adjacent block- 40 a fluid `passage 41 is formed,

which is manually Vadjustable as to size. ThefmotiveHuidis conducted to this deffvice `through the"1i'chest 17 and valves to thenozzles'. fLetzusassume ythat the valves lare turned toV lead the fluid through the advafcenozzles 35 into thehrotor.l These nozzles are so` placed that they introduce the motive fluid into the channels in the outer rotor trough from the inside and obliquely. The corrugations of the rotor rings are inclined in the same direction as Patented May 19, 1914.

motive fluid is more readily admitted. The fluid thus introduced has a tendency to drive the rotor. pansion it has a tendency to fill a greater space than that provided in the channels in lhe outer rotor trough, so some of it yvill pass through the passages between the Inozzle blocks 80 and the movable blocks 40 into the channels in the inner rotor trough, in this case entering from the outside. IIere the motive fluid Will have a further impelling effect upon the rotor. After the fluid has done its Work it passes out of the rotor troughs through the uncovered portions thereof into the inside of the rotor casing, from which it escapes through the opening 11.

On account of the Widely varying conditions in practice as to pressures, speeds and loads, I have found it desirable to provide means'for varying the proportion` of the motive fluid which isA used eX- pansivcly in the inner or secondary rotor trough. rlhis is accomplished by the simple expedient of shifting the blocks 40 in relation to the nozzle blocks 30. It may be seen that these parts may be moved together' to entirely close the passage between them, or they may be moved apart to make the In this Way a smaller or greater proportion of the motive fluid is allowed to pass into the inner rotor ring, and this proportion may be varied by a simple mechanical adjustment which may be made While the engine is running, to suit existing conditions. The nozzle blocks are also provided with reverse nozzles 36' and it is obvious that by turning the valves '31 to lead the `motive fluid through them into the outer rotor trough, the rotor Will be driven in the opposite direction.

In the modification shown in Fig. 4 the motive fluid is first introduced into the inner rotor trough through an expansion nozzle 50 in a stationary block 51. Thence some trough through a passage 52 between the fixed block 51:- and a movable block 53 similar to blocks 40 heretofore described. More or less of the fluid may be made to pass into the outer rotor trough by varying the size of this passage. Another way o accomplishing this result is to change the position of a deflect-ing vane 54 which projects from.

This is provided with a port by means of which motive fluid may be introduced into the outer rotor trough through a reverse nozzle 57 to drive the rotor in the opposite direct-ion.
